CV (constant velocity) axles are among the hardest-working parts on a vehicle, transferring power from the transmission or differential to the wheels while allowing smooth steering and suspension movement. This video breaks down how CV axles work, the role of the inner and outer joints, and why protecting the axle boots is critical to avoiding costly repairs. Whether you’re a DIY mechanic or a professional, understanding these components helps keep vehicles running safely and smoothly.

Key Takeaways

• What “CV” really means and how the axle powers the wheels
• How the inner and outer joints handle suspension and steering
• Why CV boots tear and how that leads to axle failure
